Patent IE-55257-B1 (IE)
Title: Control system for synchronous brushless motors
IPC: H02P6/14
Filed: 1982-08-30
Abstract: A motor control system wherein the motor windings are energized by sinusoidal excitation currents synthesized from prerecorded sine values. The frequency of the winding excitation currents is synchronous with the rotor movement and the phase is a function of the rotor position with respect to the stator. The phase of the winding excitation is additionally controllable as a function of speed or some other adequate system parameter. It has further been found that the total operational speed range of the system is substantially increased by further adjusting and controlling the phase of the excitation currents as a function of the desired speed.

Inventor: KLEIN HOWARD P
IPC: C08J/
Filed: 2003-08-29
Abstract: Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.

Title: Locking mechanism for moving disconnector contact - uses magnetic field of contact at high current to attract elastic insulation to block contact closure
Inventor: HOLLMANN FRITZ
IPC: H01H1/54
Filed: 1976-01-29
Abstract: The locking mechanism for moving disconnector contacts, has a blocking device. This releases when an unacceptably high current flows through through the disconnecting contacts and consists of an elastic insulating part (5) fixed to a stationary part (1) near the contact (2). The free end of the insulating part has a magnetic metal inlay (8). When a short circuit occurs the resulting electromagnetic field of the contact attracts the magnetic inlay and so that end of the elastic insulation. The edge (9) of the insulation prevents the contact (2) from moving back to touch its opposite until the current has dropped to an acceptable level.
